Rebalance mod for Freeze, need help squashing a bug

I made a mod for Freeze. An unintentional side effect of this mod is that Muddle is now dispelled by both physical and magical attacks, even attacks that do no damage such as Slow or Dischord. It only affects Muddle, not Sleep or Control. It's weird, I can't think of anything in this code that would cause that.

Symptoms:
It causes Muddle to be removed by any attack, either physical or magical, healing or damaging (or non-damaging)
Muddle is NOT removed by Debilitator, but it is removed by items such as Potion or Antidote
it does NOT cause Sleep to be removed by magical attacks (but it is removed by physical attacks)
it does NOT cause Control to be removed by magical attacks (also removed by physical attacks)
it DOES cause Control to not cause the enemy sprite to become mirrored [edit: sometimes]
when muddled, they DO become mirrored
UNLESS they were Controlled, then became Muddled, in which case they stay un-mirrored

Code:

; This changes the behaviour of Freeze:
;  Fire-elemental attacks will always remove Freeze
;  Other damaging attacks have a 50% chance of removing it
;  Physical attacks that don't do damage, or that do zero damage, have a 50% of removing it
;  Non-damaging spells will never remove it, unless they are Fire-elemental
;  Healing spells/attacks will never remove it, unless they are Fire-elemental
